WD AV Digital Video Drives

WD AV 2.5-inch (formerly WD AV-25) hard drives are optimized with SilkStream technology to capture data from up to 12 simultaneous HD video streams. With 24x7 operation, low temperature, and best-in-class reliability, WD AV 2.5-inch hard drives are ideal for DVR/PVR, IPTV and digital video surveillance applications requiring smaller form factor hard drives. 3-year limited warranty.

24x7 reliability: These drives are designed to last in high temperature always-on streaming digital audio/video environments such as PVR, DVR and IPTV systems.

Advanced Format technology: Leading edge technology delivers improved video quality and AV performance through enhanced error correction capability.

SilkStream: Optimized for smooth, continuous digital video playback of up to 12 simultaneous HD streams. SilkStream is compatible with the ATA streaming command set so CE customers can use standard streaming management and error recovery options.

Ultra-cool operation: A cool drive is a more reliable drive. WD continues to develop new and innovative ways to keep drives cool while they are operating.

Low power consumption: The drive draws less than 2 Watts while operating and a mere 4.75 Watts during spin up.

Preemptive Wear Leveling (PWL): The drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications.

Quiet: Noise levels have been minimized to less than one sone - virtually below the threshold of human hearing.
